VRay CUDA infinite mirror

[michalvobr]

Hello, I am using a VRay 3.5 for Maya 2017. I expected one issue that i cannot pass over.

 

I cannot create an infinite mirror in CUDA mode. In CPU there is not no problem. I think the problem should be that i cannot set local reflection subdivs in CUDA mode.

 

I have very low CPU vs my GPU (Nvidia Tesla), so in real case i will not render 2 mirrors but parabol in headlamp, so its needed to use a GPU CUDA mode.

 

In pictures bellow you can see what I mean, in CUDA mode I cannot get more then 3 reflections, but in CPU i can reach what i need to have. (Both render was stopped after primary bounce, for example that could be enough)

CPU:

 

Could someone help me, to find solution to get same result in GPU (CUDA)?

Did you adjust your trace depth??

On the rendering settings windows.
